Children between the ages of 6-15, diagnosed with unilateral cerebral palsy, with sufficient cognitive status to understand the evaluation commands and with reading skills will be included.

Children and their parents included in the study will be informed about the purpose of the study and the evaluations to be made and will be asked to sign a written consent form. The questions in the data collection form will be asked to individuals in a face-to-face interview. The manual skills classification system, Hand-10 questionnaire and ABILHAND-kids questionnaire will be used.

While validating the Hand10 questionnaire in children with cerebral palsy, it was planned to use the ABILHAND-kids scale, which has been previously validated for reliability and validity in cerebral palsy. It was also planned to use the hand function classification system in the evaluations. The Hand-10 questionnaire will be filled out by the child himself. The ABILHAND-kids questionnaire will be filled out by the parent. An expert will record the manuel ability system according to the hand skills.

The Manual Ability Classification System is a classification system that evaluates the hand-use skills of children with Cerebral palsy between the ages of 4 and 18 in their daily activities. It evaluates how the child holds objects on his/her own and the extent to which he/she needs assistance and adaptation when performing various functions using his/her hand in his/her daily life. It measures the general capacity to hold objects. It focuses on how the child holds objects appropriate for his/her age, regardless of the difference in function between the two hands. While Level I is the best in terms of manual skills, Level V represents the least adequate situation.

The Hand-10 (unabbreviated) questionnaire consists of 10 items. It was developed to evaluate upper extremity problems. It is a clear, short questionnaire with visual elements. It includes shoulder, elbow, wrist and hand functions. Hand-10 questionnaire assesses complaints related to hand disorders with 10 items. Patients rate their performance over the past week on a scale from 0 to 10 (0: no limitation, 10: impossible), with total scores ranging from 0 to 100. Higher scores indicate worse functional status.The presence of visual explanations allows easy application for children and the elderly. The Hand-10 questionnaire has been used to evaluate the results of lateral epicondylitis treatment and cases with carpal tunnel syndrome.

ABILHAND-Kids questionnaire is a valid and reliable questionnaire developed to assess the perceived manual skills of children with cerebral palsy or their parents. It is used in children aged 6-15. The questionnaire assesses a person's daily life activities that require upper extremity function. It consists of 21 items. Each item is evaluated between 0 and 2 points (0: impossible, 1: difficult, 2: easy). A higher score indicates better upper extremity function. There is a Turkish version of the ABILHAND-kids questionnaire.
